There are some mdoels in obj format higher in this threat, hidden somewhere among your pictures.If you have some models, please send me, any form of help will be usefull.
Anyway, if you wish more of my papercrafts reversed to models with correct UV map, write me, I have tools for that. Pepacrua things, that unfold is cool UV map, pretty wrong idea.
I know a bit about programing, but bit more about building levels as I was playing with warcraft 3 map editor, the best one I ever worked with.
And model conversion is always itching. I still cannot move models between 3DS MAX and Blender. However obj file format should be fine, along with 3ds for statics. However fbx, no matter it is open souce format comes in multiple versions and is problematic. But most model convertions, even just mesh, are problematic. I know it too well, when I crate papercrafts from game models. Right now I was digging in DOTA 2 model resources, some are nice. I would love to know their fbx type, because it seems to be the best one, all my programs import it total correct.
